Adeyemi fires treble as Celtic are humiliated in Dortmund

The Champions League has a habit of inflicting these inglorious episodes on Celtic. It is difficult to shake the notion that this big fish simply cannot swim when removed from its small domestic pond. Borussia Dortmund toyed with and teased their visitors in a match that was over as a contest long before the half-time whistle blew.

The Germans have won two out of two in this new format, having been barely tested over 180 minutes. They will have aspirations of equalling last season's memorable tournament run.

Suddenly there is pressure on Celtic's upcoming trip to Atalanta. The paucity of their showing here undermined what had been a widespread sense Celtic were better equipped for the Champions League than at any point in recent seasons. Theirs was a fragile, error-strewn display.

European football's governing body were in profit from this fixture before a ball was kicked. A fine will inevitably be issued after the teams emerged to giant banners in the Yellow Wall, branding Uefa as "mafia." Underneath read the slogan: "You don't care about the sport, all you care about is money." Pyrotechnics from the Celtic support at the same point will also trigger a sanction.

A madcap opening soon took attention away from what had transpired in the stands. Celtic did the very thing they were so anxious to avoid by handing impetus to Dortmund, only to claw their way back into proceedings and concede a second goal that was as defensively soft as the hosts' first.
